AUTOMATIC THREAD-BOARD LIFTER FOR SPINNING-FRAMES.

I5PEGIFICATION forming part of Letters Patent No; 737,084, dated August 25, 1903.

Applicationfiled September 17,1902. SarialNo.123,675. (Noniodel) To all whom it may concern.-

Be it known that I, NAROISSE N. S. DAUDE- LIN, a citizen of the United States, residing at Fall River, in the countyg'of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Automatic Thread-Board Lifters for Spinning and Twisting Frames, of which thefollowing is a specification.

This invention relates to spinning and twisting frames; and its object is to relieve the yarn from the strain which is caused by the short distance between the ring-traveler and the guide-wire on the thread-board when the ring-rail is at the highest point of the the yarn to turn at a sharp angle where it passes through the guide-wire and ring-trav- This trouble is aggravated when a large ring is used.

A further object of my invention is to inring-rail is near the bottom of the wind.

I accomplish these results by making the thread-board vertically movable and providing means for automatically lifting it at the proper time, as hereinafter set forth, and particularly pointed out in the claims.

In the accompanyingdrawings, Figure 1 is a sectional end elevation of a ring-spinning frame embodying my invention. Fig. 2 is a similar view of one thread-board when raised.

Fig. 3 is a front elevationof' the upper part of a bobbin and adjacentIparts. Fig. 4 is a perspective view of one of the" rock-shaft bearings, and Figs. 5 and 6 show two views of the slide for said bearing.

The frame 1 supports'on each side the vertical spindles 2, driven by bands 3 from the driving-drum 4. The ring-rails 5 are vertically movable to feed the thread to the bobbins 6. The thread is brought through the ,rolls 7, supported on top of the frame 1,

and is ledthrougha guide-eye 8 on the thread- I board 9, attached to the frame'l above the The mechanism includes a heart detaileddescription of them or their mode of operation.

My improvement lies in part in the thread-' boards 9, which I render vertically movable, preferablyby hinging them tothe frame 1. Attached to each thread-board is an arm 12, and adjacent to each arm is an elbow-lever having two arms 13 and 14', the latter carrying a pin 15, bearing on said arm. The elbowlever is fulcrumed in an adjustable bearing supportedon a bar 16, fastened to the frame of the machine. The bearing is formed in a boss 17 at one end of a, plate 18, having a lon-- 1 gitudinal slot 19. The bar 16 also has a slot 20 at right angles to the slot 19. A slide 21 is interposed between the-bar'and theplate, consisting of a plate having a shallow groove 22 on one side to fit the bar 16, and a shallow groove 23 on the other side at right angles to .the groove 22 and fitting the plate 18. The

slide also has a central hole 24 for the clamping-bolt 25, which passes transversely through v:

the bar, the slide, and the plate; This device enables the bearing for the elbow-lever to be adjusted both lengthwise and transversely of-the bar 16. On one side of the machine the pin-carrying leg 14 of the elbowlever is the upper, andjonthe other side of the machine it is the lower.- The other legs of the levers are connected by a rod 26, which is pivoted to them and is composed oftwo iparts adjustable lengthwise bya slot 27 and clamping-bolt 28, so that the length of the rod can be altered as desired.

Inorder to operate all the elbow-levers simultaneously, a rock-shaft 29 runs through all the bosses 17. on one side of the machine,

.and all the elbow-levers are secured to said shaft by set-screws 30. The rock-shaft has at one end a rock-arm 31, connected by a lon- ,bolt and bearing on the periphery of the cam 10. I

The operation of my invention is as follows:

At every revolution of the cam the lever is lifted and lowered, and the rock-shaft is rocked alternately in opposite directions.

gitudinally-adjustable rod 32 with one end of t This causes the pins in the elbow-levers to depress all the arms 12, and thereby raise the thread-boards. This, as previously explained, lengthens the distance between the ring-traveler 36 and the guide-eye 8 on the thread-board, and thus enlarges the angle of the thread at these points and relieves the strain. The raising of the thread-boards takes place simultaneously during the time the ring-rail is traversing the upper part of its Wind.

It will be seen that in machines where the thread-board is vertically adjustable on the frame my invention permits it to be set lower than usual, so that in the case of a long traverse ballooning of the yarn is largely prevented and better and stronger yarn is the result.

What I claim as new, and desire to secure by Letters Patent of the United States, is-

l. The combination with two hinged threadboards each having an arm, of a rock-shaft adjustably supported adjacent to each arm, an elbow-lever on each shaft having a pin in one leg bearing on said arm, a lengthwise-adj ustabie rod connecting the other legs of said elbow-levers, arock-arm on one of said shafts, a lever, and an adjustable rod connecting said lever and said rock-arm.

2. In a ring spinning and twisting frame, the combination with two hinged threadboards each having an arm secured thereto, of stationary bars secured to the frame of the machine, bearings adjustably secured to said bars, rock-shafts journaled in said bearings, an elbow-lever on each shaft one leg of which engages with but is not attached to the arm on the adjacent thread-board, a length- Wise-adjustable rod connecting the other legs of said elbow-levers, a rock-arm on one of said shafts,and means for actuating said rockarm.

In Witness whereof I have hereunto set my hand this 11th day of September, 1902.
